Silicosis Lawsuit: Engineered Stone and Quartz Claims

Countertop workers diagnosed with silicosis after cutting artificial stone slabs are pursuing legal claims against manufacturers for failure to warn of severe silica hazards.

You can file a lawsuit against artificial stone manufacturers and distributors if you developed silicosis from cutting, grinding, or polishing engineered quartz countertop slabs. At LawfareClaims.org, we help workers and families understand these product liability claims and determine their legal options.

Silicosis is incurable. It is also progressive and potentially fatal. The disease is caused by inhaling respirable crystalline silica (RCS) dust. Fabricators cutting quartz countertops inhale microscopic mineral particles that scar lung tissue, causing irreversible damage that often requires a lung transplant. The disease also raises the risk of lung cancer, chronic obstructive pulmonary disease (COPD), tuberculosis, and chronic kidney disease.

These lawsuits work differently than a workers' compensation claim. A workers' comp claim only involves your direct employer. A product liability lawsuit instead targets the corporations that manufacture and supply the engineered stone slabs themselves. Lawsuits allege these manufacturers produced inherently hazardous materials without providing sufficient warnings or safe handling instructions to the fabrication shops processing their slabs.

Engineered Stone and How It Causes Lung Disease

Inhaling respirable crystalline silica during countertop fabrication leads directly to silicosis, an incurable occupational lung disease. When workers cut, grind, hone, or polish stone slabs, mechanical friction crushes crystalline quartz into airborne micro-particles. These particles penetrate deep into lung alveoli. Immune cells cannot break them down. The resulting inflammatory response generates dense fibrous scar tissue that permanently impairs the lungs' ability to extract oxygen from the air.

Engineered stone, frequently sold under popular brand names for quartz countertop slabs, carries a much higher risk of rapid lung damage than traditional quarried rock. Manufacturers make it by combining crushed stone with polymer resins and color pigments. The result is an artificial composite material that is typically much higher in crystalline silica content than natural granite or marble.

That higher silica content is the danger. Dry cutting, or wet fabrication without adequate controls, throws off heavy concentrations of toxic dust. Fabricators who shape these slabs without effective engineering controls inhale dense clouds of fine silica. Medical researchers have linked this intense exposure to accelerated silicosis, an aggressive subtype of the disease that causes rapid respiratory decline within a few years of initial exposure.

Workplace Safety Standards and the 2026 Federal Hazard Alert

Federal regulators enforce strict limits on workplace silica dust. They have also recently warned that stone countertop fabrication specifically creates severe exposure risks requiring comprehensive controls. Under the crystalline silica standard adopted in 2016 for general industry and construction, the Occupational Safety and Health Administration (OSHA) sets a permissible exposure limit (PEL) of 50 micrograms of respirable crystalline silica per cubic meter of air, calculated as an 8-hour time-weighted average.

Standard workplace precautions are often not enough. On February 26, 2026, the National Institute for Occupational Safety and Health (NIOSH) and OSHA jointly updated a hazard alert on this exact point. It carries two designations: NIOSH Publication No. 2026-101 and OSHA HA-3768-2026. The alert warns that employees who manufacture, finish, and install natural and engineered stone countertops face serious risks of debilitating lung disease.

Respiratory protection alone cannot eliminate the danger, the joint alert says. It calls for a layered hierarchy of controls instead: eliminating or substituting high-silica materials wherever possible, engineering controls such as local exhaust ventilation and continuous water-delivery systems for wet-cutting, strict administrative controls, employee exposure monitoring, and fitted personal protective equipment. The goal is keeping respirable dust out of a fabricator's breathing zone.

Scale of the Outbreak and California's Regulatory Response

State health tracking shows the outbreak of accelerated silicosis has heavily impacted immigrant fabricators working in small cutting and polishing shops. The California Department of Public Health reports that affected workers are disproportionately Latino immigrant men. Many were exposed in independent fabrication businesses with limited dust suppression equipment. State officials track these cases on an ongoing monitoring dashboard, so the official count climbs continuously as more diagnoses are confirmed.

The human toll is severe. According to public health tracking reported by KQED in May 2026, California health officials had documented more than 560 stoneworkers diagnosed with the aggressive accelerated form of silicosis. At least 31 workers had died since 2019. Roughly 58 to 60 had undergone a lung transplant.

These outcomes pushed California regulators toward unprecedented restrictions. In December 2023, the state adopted an emergency silica standard targeting materials with more than 10% crystalline silica; it became permanent in February 2025. Then, on May 22, 2026, the California Occupational Safety and Health Standards Board granted a petition from medical organizations and directed Cal/OSHA to fast-track a stricter emergency regulation, one that would prohibit fabricating or installing engineered stone above a 1% crystalline silica threshold. That proposed 1% rule is still advancing through state rulemaking, not yet a final regulation.

The Landmark 2024 Reyes-Gonzalez Jury Verdict

A California trial delivered the first civil liability verdict against engineered stone manufacturers for causing occupational silicosis. In August 2024, a Los Angeles County Superior Court jury awarded $52,437,366 to Gustavo Reyes-Gonzalez, a countertop fabrication worker who spent 15 years cutting and polishing artificial stone slabs in Los Angeles and Orange County shops.

Reyes-Gonzalez developed severe accelerated silicosis that permanently destroyed his respiratory system. He ultimately needed a double lung transplant to survive. In the verdict, announced via a PR Newswire release, the jury found engineered stone manufacturers Caesarstone and Cambria, along with stone distributor Color Marble, legally liable for his injuries.

The jury split responsibility across the supply chain: 15% of the fault to Caesarstone, 10% to Cambria, 2.5% to distributor Color Marble, and 2.5% to Reyes-Gonzalez himself, with the remainder allocated to other non-party entities. It was the first jury trial verdict of its kind in the United States involving engineered stone silicosis.

Current Litigation Status and Procedural Posture

Engineered stone silicosis lawsuits are currently proceeding as individual product liability actions in state trial courts, not as a consolidated federal proceeding. According to the Judicial Panel on Multidistrict Litigation (JPML) pending dockets, no federal multidistrict litigation (MDL) exists for these claims. No certified nationwide or statewide class action exists either.

That means injured workers must file individual civil lawsuits in the appropriate state court. A large share of this litigation is concentrated in California, reflecting the large number of fabrication shops and documented diagnoses there. Our guides to mass torts and what is a mass tort explain how individual claims differ from a collective action.

Plaintiffs in these lawsuits assert claims grounded in defective product claims, primarily failure to warn. The complaints allege manufacturers and wholesale distributors knew, or should have known, that processing their high-silica slabs generated lethal levels of respirable dust, and failed to provide adequate safety warnings or handling instructions to fabricators. No global or aggregate settlement program exists. Each case must be prepared for individual settlement negotiations or trial.

Eligibility Criteria and Gathering Evidence

Qualifying for an engineered stone silicosis lawsuit requires two things: a formal medical diagnosis, and a documented occupational history of processing artificial quartz slabs. Attorneys handling these claims examine several specific factual elements before taking a case.

Legal teams typically look at four categories of evidence:

Documented medical diagnosis: an official diagnosis of silicosis, accelerated silicosis, or a related respirable silica condition such as lung cancer, COPD, or chronic kidney disease, confirmed through chest X-rays, high-resolution CT scans, pulmonary function tests, or lung biopsy pathology.

Occupational exposure history: a clear history of working as a countertop fabricator, stone cutter, polisher, saw operator, or installer who handled engineered quartz materials.

Slab brand identification: evidence identifying the specific brands of artificial stone processed in your shop, such as purchase orders, delivery invoices, remnant slab markings, or witness statements from shop owners and co-workers.

Employer and employment records: tax forms, pay stubs, safety logs, or union records showing the duration and location of your employment in stone fabrication shops.

Statutes of Limitations and Compensation

Every silicosis lawsuit is subject to a statute of limitations, a strict statutory deadline that bars recovery if you file too late. For personal injury claims, state deadlines generally run one to three years, though the exact clock depends on the law of the state where you worked or reside. In a latent disease case like this one, that deadline typically starts on the date you received an official diagnosis, or when you reasonably should have discovered your illness was caused by occupational silica exposure.

Compensation in an individual lawsuit can include both economic and non-economic damages. Economic damages cover tangible financial losses: past hospital bills, the cost of lung transplant surgery, ongoing immunosuppressive medications, and projected future lost wages. Non-economic damages address physical pain, emotional suffering, reduced life expectancy, and the diminished quality of life that comes with chronic oxygen dependency.

No global settlement fund has been established, and statutory deadlines are rigid. Consulting a qualified personal injury attorney promptly helps protect your rights. Surviving spouses and dependent family members may also have the legal right to pursue a wrongful death claim if a loved one died from complications of accelerated silicosis.

Frequently Asked Questions

What is the silicosis lawsuit about?

The silicosis lawsuit is a product liability action filed by countertop fabrication workers against manufacturers and distributors of engineered stone quartz slabs. Lawsuits allege that manufacturers knew their high-silica composite materials produced lethal respirable dust when cut, ground, or polished, yet failed to provide adequate safety warnings or handling protocols to the shops working with their slabs.

Why is engineered stone more dangerous than natural stone?

Engineered stone is an artificial material manufactured from crushed stone bound with polymer resin, and it is typically much higher in crystalline silica content than natural granite or marble. When fabricators cut or polish these quartz slabs, the higher concentration of crystalline silica releases vast amounts of microscopic dust that causes severe lung scarring and accelerated forms of silicosis.

Is there a silicosis MDL or class action?

No federal multidistrict litigation (MDL) docket or certified class action currently exists for engineered stone silicosis claims. Lawsuits are being filed, investigated, and litigated as individual personal injury and product liability cases in state trial courts across the country, with a large concentration of case activity in California.

Has anyone won a silicosis case yet?

Yes, in August 2024, a Los Angeles County Superior Court jury awarded $52,437,366 to Gustavo Reyes-Gonzalez, an injured stone fabricator who required a double lung transplant after cutting artificial quartz slabs for 15 years. The jury found manufacturers Caesarstone and Cambria, along with distributor Color Marble, legally liable for his illness.

Who may qualify to file a silicosis lawsuit?

You may qualify if you worked in the stone fabrication industry cutting, grinding, or polishing engineered quartz countertops and were subsequently diagnosed with silicosis, accelerated silicosis, lung cancer, COPD, or kidney disease. A legal claim requires medical records documenting your diagnosis and proof of occupational exposure to artificial stone products.

What health problems can silica exposure cause?

Inhaling respirable crystalline silica dust causes silicosis, an incurable lung disease that leads to progressive scarring and respiratory failure. In addition to silicosis, prolonged silica dust exposure raises the risk of developing lung cancer, chronic obstructive pulmonary disease (COPD), pulmonary tuberculosis, and chronic kidney disease.

How long do I have to file a silicosis claim?

Statutes of limitations for personal injury lawsuits vary by state, generally running between one and three years from the date of your formal medical diagnosis or discovery that your lung disease was tied to silica exposure. Because statutory deadlines differ across jurisdictions, you should consult an attorney promptly to evaluate your filing window.
